- 2 Claims.

This invention relates to a support for a telephone, and, more particularly, to a wall type mounting for a hand telephone.

An object of this invention is to simplify the structure of mountings for telephones.

A feature of this invention comprises a hand telephone mounting having a wall portion to be secured to a mounting surface and another wall portion disposed at an obtuse angle to the first wall portion and the surface on which it is mounted.

Another feature comprises such a mounting in which the second wall portion carries a support or hook to receive one end of a hand telephone.

A further feature comprises such a mounting in which the second wall portion closes an oblique, rectangular open end of the casing.

Still another feature comprises such a mounting in which the casing contains all the usual instrumentalities provided at a subscribers station, i. e., condenser, induction coil, ringer, terminal block, and the second wall portion supports a switchingspring assembly on its inner side and associated with the hook or support for the hand telephone.

Other and further features will be evident from the description which follows hereinafter.

A more complete understanding of this invention will be obtained from the detailed description which follows taken in conjunction with the appended drawings wherein:

Fig. 1 is a plan View of a support or mounting for a hand telephone in accordance with the invention;

Fig. 2 is a front elevational view of the device of Fig. 1;

Fig. 3 is an exploded view of the device of Fig. 1;

Fig. 4 is a plan view of the device of Fig. 1 partly broken away to show the telephone instrumentalities mounted therein;

Fig. 5 is an elevational view to a reduced scale of the device of Fig. 1 mounted on a wall and supporting a hand telephone;

Fig. 6 is a plan view of the device of Fig. 1 mounted on a vertical surface facing to the left; and

Fig. '7 is a plan View of the device of Fig. 1 mounted on a vertical surface facing to the right.

This invention is disclosed embodied in a support or mounting ill for a hand telephone ll comprising a receiver l2, a transmitter l3 and .a common support or handle 14. The mounting comprises a housing, casing or enclosure l5 comto improve and hand 1935, Serial No. 28,408

prising walls l6, l1, 18, I9 and 20 defining a chamber 2l,, and having an obliquely disposed rectangular open-end 22. The open-end 22 is closed by a substantially rectangular wall portion or plate member 23 that is secured to the case by 5 suitable symmetrically disposed fastening means, for instance, the screws 24 that thread into the tapped drillings 25 in the thickened portions or lugs 26 of the casing walls. This arrangement permits of rotation of the casing through 180 10 degrees while the wall member 23 remains in its original position, without affecting the ease of attachment of the member 23 to the casing. This means that the casing may be mounted on a vertical surface facing either to the right or to the 15 left, for instance, on either side of a desk, and yet the member 23 will be positioned with the same end uppermost. In Fig. 6, the mounting is shown attached to the left side wall or surface 21 of a desk 28 and in Fig. 7, to the right side 0 wall or surface 29 of the desk. In each case, the wall member 23 is obliquely disposed and, like the open end 22 of the casing, makes an obtuse angle with the wall portion 11 and the surface 21 or 29. In Fig. 5, the casing is shown 25 supported on a vertical surface 30, for instance, the wall of a room, the wall portion I9 being secured thereto.

The member 23 comprises a hollow, forward extension 3! adapted to receive and support a 30 calling device or dial 32 and an integral lug 33 projecting into the casing from its inner surface 34 and supporting a plurality of switching springs 35. It supports a switchhook 36, having a portion 31 on the front side 38 adapted to receive the 35 receiver end of the hand telephone and a portion 39 on the inner side 34 adapted for engagement with the switching springs. The switchhook is pivotally mounted on a pair of lugs 40 (only one of which is shown) projecting from the inner side 40 of the member 23. The broken line ll indicates the position of the switchhook when the hand telephone is supported thereby, the inner surface of the wall portion l6 acting as a stop for the end portion 42.

The casing is adapted to enclose and to support the usual instrumentalities provided at a subscribers station, that is, a signaling means or ringer 43, a condenser 44, an induction coil 65, a plate 46 of insulation for terminals, and if desired, an electrical filter 41 for preventing interference with radio reception in the vicinity of the telephone when the dial is being operated. An opening 48 is provided for a cord (not shown) and additional openings (not shown) may be provided in wall portion 29 for the egress of ringer tone.

The support or mounting described is compact and readily assembled and is capable of being quickly and simply mounted on any suitable vertical surface, particularly on either side of a desk, with the hand telephone and the dial readily and conveniently accessible to the hands of the user.

While this invention has been disclosed. with reference to a specific embodiment, it is to be unthe derstood that it is to be considered as limitedin scope by the appended claims only.

What is claimed is: 1. A support for a hand telephone comprising a casing defined by a pluralityof planar wall pertions for housing the usual instrumentalities pro- H vided at a subscribers station, e. g., induction coil, I condenser, ringer, terminal block, and having an 3 open-end portion angularly disposed with reference to said wall portions, and a closure member for said open-end comprising a plate member having an outwardly projecting hollow extension to receive and support a calling dial and having an inwardly extending support for switching springs, and a support for a hand telephone having a portion on the outside of said closure member to receive the receiver end of the hand telephone, and a pivotally supported portion on the inside of said closure member adapted for engagement With switching springs, said closure member being angularly disposed with'reference to the wall portions of said casing.

2. A mounting for a telephone handset for attachment to a desk or table comprising a casing, a cover therefor, and a calling dial, a switchhook and switching springs mounted on said cover, said dial being mounted below said switchhook, Whereby it is operable only when the handset is removed from the switchhook, said cover being removable and said casing being provided with an angularly disposed portion such that the dial and switchhookiace the center of the desk or table regard less of Whether the casing is mounted on the right or left-hand side of he desk or table.
